' u No. 859,909.

To all whom it may concern: n

Be it known that l, AnNE H. BERG, a citizen of the United States, residing at Clarkiield, in the county.v

determine whether the particular party called has been obtained and also owing to the fact that even ii the proper party has in the first instance been obtained any other subscriber might byfmerely removing his receiver, listen to the party talking without his knowledge.

The object of the present invention is vthe provision of an attachment which will overcome this difficulty by causing a particular signal to be given whenever the receiver of any phone in the line is taken off its hook, which signal is peculiar to that particular phone and may be heard .by any other party using the line, therebyk notifying such party that that particular phone is on the line.

A further object of the invention is the provision of a signal of this character which is mechanically operated by the receiver hook when the receiver is lifted therefrom. y

A further objectof the invention is the provision of a signal of this 'character in which signaling means of two distinct characters are employed, whereby the same may be readily heard by any of the subscribers to the line, and whereby the signal may be adapted'for a number of telephones on the same line by varying the order ofsounding the distinct signaling mechanism.

Other objects f the invention will be apparent from the detailed` description hereinafter when. read in connection with the accompanying drawings forming a part hereof, wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to similar parts in the several views.

In the drawings: Figure 1 is an elevation of the telephone casing the front thereof being removed. Fig. 2 is a sectional vie'w of the attachment.

Referring now more particularly to the drawing A designates the telephone casing, which is of the usual construction, and in which is pivotally mounted the receiver hook B, which'vis, as is usual in this class of devices, normally maintained in its uppermost posii tion bya spring b. Secured within the telephone casing above the receiver hook B is a support C upon which is'mounted a bell or gong Pivotally mounted upon the support C is a hammer or clapper E, which Speicication of Letters Patent.

isdesigned to coperate with the'gong D. Positioned above the support C and rigidly secured thereto is a plate or support F, which is provided with an elongated slot extending inwardly from the front edge thereof. The slot f in the plate F is occupied by a thin metallic tongue G which is rigidly secured in any suitable manner at its rear end only and which is leper E which is designed so coperate vwith the gong G is preferably rigidly secured to ashaft e which is journaled in suitable bearings mounted upon the sup- A port C and from which shaft extends an Varm e which is provided at its forward end with guides in which works the free end of a leaf spring El; which is secured to the support C and normally serves to hold the clapl per in close proximity to the gong.

H designates an arm which is pivotally connected to the receiver hook B and extends upwardly therefrom through a suitable guide opening inthe support C. The arm H is provided with a plurality of inclined projections h extending from the rear face thereof signed when vibrated to give forth a sound. The clapwhich project into the entrance of the slot f in the -plate F and are designed. to successively engage the free endqJ of the metallic tongue G when the arm H is elevated by reason of the receiver being removed from the receiver hook. The arm H is also provided along one edge thereof with a projection hY which is designed during the upward movement of said arm' to engage with free end of the leaf spring E and elevate the same for a slight distance. As the spring E is vconnected with the arm e which extends from the shaft of the clapper E it will be apparent that said arm will also be elevated slightly'until the projection h. passes the free end of the spring E, which will permit said spring to quickly return to its normal position and through its connection with the arm e2l will cause the gong to sound the bell. l

In the form of my invention illustrated in the drawing, the rod H is provided with two projections h which successively engage the metallic tongue G and with a single projection which subsequently engages the leaf spring vEf, so that when the receiver is removed from the receiver hook, two distinct sounds of the thin metallic tongue G will be produced and one ring. ltl

I do not desire to limit myself to the precise form and u n *11o construction shown in the drawings, as it is obvious that many minor changes might be made, thereto without departing from the spirit of the invention.

Having thus described the invention, what is claimed is:

1. ln a device ot the character described. a telephone hook. and a mechanically operated signal, adapted to be actuated when the receiver is removed from said hook.

L. ln a device of the character described, a l'eceiver hook, a plurality of distinctive mechanically operated signals adapted to he actuated'when the receiver is removed from its hook.

It. in a device of the character described, a receiver hook. .i plurality of audibly distinctive signals, and means for successively actuating said sianals when the receiver is removed from said hook. l

-l. ln a device of the character described, a pivoted receiver hook. a spring for normally elevating said hook, a mechanicallyoperated signal, and means for actuating said signal upon the eleva-tion of said receiver hook.

[n n device of the character described, a receiver hook. au arln secured to said receiver hook and movable therewith. said arm being provided with a projection thereon. and a signal having an actuating portion designed to be engaged by the projection on said arm during the upward movement of the receiver hook.

C. In a device of the character described, a receiver hook,

an arm secured thereto, and provided with a plurality of projections thereon. and -a plurality of signaling devices provided with actuating,r portions adapted to be engaged by the projections onsad arm during the upward movement of the receiver hook.

7. In a device of the character described, a receiver hook` an arm secured thereto and provided with n plurality lof projections thereon, and a plurality of audibly distinctive signals provided with actuating.: portions designed to be engaged by the projections on said arm during.: the upward movement of the receiver h'ook.

N. In a device of the character described, a telephone hook, and a mechanically operated signal, and means for intermittently actuating.: said signal when the receiver is removed from said hook.

il. In a device of the character described, a receivel' hook; an arm secured thereto and provided with a plurality of projections thereon. and a signal having an actuating portion designed to be successively engaged by the projections on said arm wl'en the receiver is removed from its hook.

10. I n combination with :Ltelephonc casing, a spring ,actuated receiver hook pivoted therein, ya support within the casing` a plurality of mechanically operated signals of different. charm-ters mounted on said support, each of said signals being provided with :urac-mating portion, and a Amember carried by the receiver hook and provided with Vprojections adapted to engagethe actuating portions of `the different signals upon movement of the receiver hook. lu testimony whereof l ailix my signature in presence or two witnesses.
